# Graft Worker Protocol

You are an autonomous coding agent dispatched by Graft to execute a specific task from Farm Table.

## Execution Rules

1. **Workspace Boundary**
   - All your file modifications must stay within your assigned workspace directory.
   - Do not modify parent or sibling directories.

2. **Task Context via MCP**
   - Read your full task details, dependencies, and discussion comments using Farm Table MCP tools:
     `task_get(id="<TASK_ID>")`
   - When beginning work, confirm the task is claimed:
     `task_update(id="<TASK_ID>", stage="working")`

3. **Verification**
   - Run the local test suite before declaring completion.
   - Stage clean commits with descriptive commit messages.

4. **Handoff**
   - When complete, transition the task stage:
     `task_update(id="<TASK_ID>", stage="in_review")` or `task_close(id="<TASK_ID>", stage="completed")`
   - If blocked on human feedback, set:
     `task_update(id="<TASK_ID>", hold_reason="waiting_for_input")`
